To all whom it may concern Be it known that I, FRED S. EDINGER, a

citizen of the United States, residing at Berkeley, in the county of Alameda and State of California, have invented certain new and useful Improvements in Apparatus for Transferring Earth and other Excavated fication.

My invention relates to apparatus for ex cavating and removing earth and other material, and particularly to apparatus in which a transferring structure is used for receiving the material from an excavating machine and delivering it at a point too far distant for direct delivery by said machine. In apparatus of this kind, it is usual to employ some form of cantaliver structure with conveying means thereon, said structure extending from the range of delivery of the excavating machine to the point of destination of the material. This structure, which is mounted upon skids or a-movable base to adapt it totravel along the work, is commonly either successively anchored to. and .released from any convenient or lnconvenient fixed'point, or it is supported on a wide base to give itstability. In any case, it is moved along and brought to its proper position relatively to the excavating'machine with which it is associated, entirelyindependently of said machine, and it is often diflicult to find or to prepare a proper anchorage for it, and in case its movable base is a wide one, it is a loss in time and labor to prepare a berm 1 or bench wide enough for said base.

It is the object of my invention to provide an organized apparatus or unit which will include both the excavating machine and the cantaliver transfer structure, said object being attained by anchoring the structure to the excavating machine, whereby the weight of the latter is utilized for this purpose, resulting, thus, in a convenient and perfectly available anchor and in a relatively narrow traveling'base for the cantaliver structure and a corresponding narrow berm or bench for said base.

To this end my invention consists in the novel apparatus which I shall now fully describe by reference to the accompanying drawings, in which' Figure 1 is a side elevation of the apparatus; Fig. 2 is a plan of the same.

' 1 is an excavation. I

2 is a berm or bench between the excavation and the toe of the slope 3 of the embankment or spoil bank 4 thrown up on the natural surface. In the excavation is an excavating machine 5. This may be of any character adapted for the purpose. For

illustration, I show it, in a general way, as

a steam-shovel, of which 6 is the A-frame, 7 the boom and 8 the dipper. This machine is movable as usual, being here shown as having wheels 10' running on tracks 11. On the berm 2 is a base 12 adapted to move in a path parallel with the path of the excavatin machine 5. This base may be any movable structure or device, preferably a frame to move on skids 13, as I here show it. This movable frame or base 12 carries the cantaliver structure of the transferring part of the apparatus.

The cantaliver may be of any suitable construction, involving a transfer floor 14 projecting from a point or line within the radius or range of delivery of the excavator dipper to the point to which the material is to be transferred, in this instance the embankment 4, said floor carrying any suitable device or means for conveying the material received fromthe dipper and dumping it at its destination. These conveying means preferably comprisea car 15, operating on a track 16, as illustrated. The remainder of the cantaliver structure may be of various constructions, forms and arrangements to stiffen and brace it and to enable it to be properly balanced and to be anchored to tended for any use in which material 'exca- A-frame, the base of which is secured to each side of the transfer floor 14 at 20, and the body of which projects, at 'anfu pward in-- clinatio-n, to a point above the excavating machine 5. Suitable rods 01" wire cables-21 unite the several parts of-the cantaliver structure, and said structure as a whole is anchored tothe'excavating 'ma'chine 5 in suitable manner, as, for example, by the connection 22,which is here shown as an adiustable block and tackle; arrangement n order to vary the inchnatlon of the transfer floor 14, which variation may take place about the foot of thebent-frame l'las a center. for which purpose said foot is preferably rounded; as I indicate at 23, to enable the whole cantaliver structure torock upon said foot. as the anchor tackle 22isadjusted. This anchorconnection 22 is hereshow-nas extending from the free end of the gaffframelQ .downto the top of the A frame 6 of the excavating machine 5. a

24 indicates a platform carried by the movable base 14- for the hoisting means of the car 15. The'apparatus as whole is, in-

vated has to .betransferred to a point too far distant from the excavating machine for direct delivery by, said machine-- "By anchoring the cantaliver-structure to,

" 'the excavating machine, I utilize the weight to in order to support and balance the cantallver transfer structure.

My invention as hereinabove described comprises i an organized apparatus consist: mgiof two co-actm-g and interconnected units, whereas in devices of this nature, as commonly constructed and used, theexca vating machine-is either entirely separate from-the'conveying apparatus, and is moved I and anchored separately therefrom, or else the two are combined in one unit upon a Y common support, in whlch case the base is,

unwieldy and necessitates heavy and costly,

foundations or tracks. Bye-my two unit Copies ofithis patent may be obtained for construction, however, I secure the greatest flexibility ofoperation, and at the same time anchoring the conveying apparatus,-- thus eliminating the necessity for an unduly large support therefor,

a transfer'floor extending from the range of delivery of the excavating machlne to the point of destination of the material excavated; conveying means carried by said transfer floor adapted to receive the material from the excavating machine and to transport t to its discharge; a substantially upright frame for supporting said transfer floor; a movablebase. upon. which said upright frame rests a counter-balance gaff attached to said supporting. frame and said opposite to the latter; and a connection an choring said' gaff tofthe excavating machine.

2. An apparatus forth e described 'purpose consisting of an excavating'machine;
